FITTING DIAGONAL ANCHORS
In everyday site practice, there are various different ways of preparing positioning
points for diagonal anchors at a precise angle (usually 45°), depending on the site
situation.
The following examples show several possible and effective options. These apply
equally to the use of either pigtail anchors or stop-anchors.
FIT THE ANCHORS AT A 45° ANGLE.
- Fitting a diagonal anchor at a steeper angle than this increases the load.
- If the angle is increased by 10° (i.e. to 55°), this increases the load on the
tie-rod by over 20% and may thus lead to serious overloading.

WOODEN TEMPLATE
- This method permits variable
distribution of the positioning points,
and can therefore be reused in any
situation.
- Alternatively, a clear, fixed arrange-
ment of the positioning points can be
made with naildown wedges of square-
sawn timber.
- Many variations are possible on this
theme, meaning that this example can
be optimized for the case in hand.
ANCHOR HOLDERS AND CLEARANCE
CONES
- For precise location and directionally
stable fitting of anchoring components
at a 45° angle.
- Mount an anchor holder on the tie-rod,
and fasten it to the top reinforcement.
- Screw in the clearance cone.
- After pouring, replace the clearance
cone with a she-bolt.
